Question

1. how does the chronological structure of the section piedmont meets plain help develop the thesis of the article?

by describing how long ago the tectonic shift began
by explaining the geologic events that formed the fall line
by discussing how metamorphic rocks are created
by showing that the escarp... uses water to flow downhill

Explanation:

To determine the answer, we analyze the options. The question is about how a chronological structure in a section helps develop the article's thesis. A chronological structure (order of time) for geological events would explain the sequence of events forming the fall line. Option A focuses on when a shift began, not the thesis development. Option C is about metamorphic rock creation, not related to the fall line or thesis. Option D (partially visible) seems about escarpment and water flow, not chronological event explanation. Option B, explaining geologic events (in time order) that formed the fall line, aligns with using chronological structure to develop the thesis.

Answer:

B. By explaining the geologic events that formed the fall line
